URL Shortening

We support URL shortening for both SMS and SMS Campaign, making it easier to craft a more digestible message for your recipients and also allowing you to save characters in your messages.

Some limitations to be aware of are:

• Only valid links are processed. A valid URL must include a proper protocol (e.g., http:// or https:// ) and a valid domain (e.g., example.com ).
  • The following links are considered invalid links:
    • google.com (does not contain a valid protocol)
    • www.google.com (does not contain a valid protocol)
    • https://examplecom (does not contain a valid domain)
• We can shorten links up to 250 characters in length.

SMS

For SMS messages, URL shortening automatically detects and replaces one URL in each message with a shortened link in the format smsu.io/xxxxxx. The xxxxxx placeholder represents a unique six-character alphanumeric string that is generated for each recipient during the actual sending process.

You should use this endpoint if you wish to send out a link that is specific to the recipient, such as order tracking links, or customised feedback forms.

Link tracking and statistics for SMS messages using shortened URLs are not yet available.

SMS Campaign

We support URL shortening and subsequent link tracking within SMS campaigns.

When using the short URL functionality in SMS Campaign, all recipients will receive a shortened link in the format smsu.io/xxxxx. The xxxxx placeholder represents a unique five-character alphanumeric string that is generated for each recipient during the actual sending process.

You should use this endpoint if you're sending out the same link to many recipients and wish to track its engagement such as whether the link was opened.
